To evaluate the long-term oncologic results of supracricoid laryngectomy with cricohyoidoepiglottopexy (CHEP) for laryngeal cancer. A 35-year retrospective study concerning 291 patients treated by supracricoid laryngectomy with CHEP for laryngeal cancer was performed. The following postoperative data were studied: recurrence rates (lymph node and laryngeal), distant metastases and second cancer. The mortality rate and overall survival were estimated by the Kaplan-Meier method. The postoperative mortality was 1.03 %. 23 patients were lost to follow-up. The 3-year survival rate was 84 % and the 5-year survival rate was 80 %. 12 patients developed distant metastasis. 31 patients developed a second cancer. The local (laryngeal) control rate was 93.94 % and the regional (cervical lymph node) control rate was 92.05 %. In multivariate analysis, the occurrence of a second non-ENT cancer and metastasis as well as margins involvement were reliable to mortality. Supracricoid laryngectomy with CHEP appears to be associated with very good long-term oncologic results and still has a place in the management of T1, T2 and selected T3 glottic cancers.

Although the incidence of breast cancer has increased, breast cancer mortality has decreased, likely as a result of both breast cancer screening and improved treatment. There are well over two million breast cancer survivors in the United States for whom appropriate surveillance continues to be a subject of controversy. The guidelines from the American Society of Clinical Oncology (ASCO) and the American College of Physicians are clear: only performance of yearly screening mammography is supported by evidence. Although advanced imaging technologies and sophisticated circulating tumor biomarker studies are exquisitely sensitive for the detection of recurrent breast cancer, there is no proof that earlier detection of metastases will improve outcome. A lack of specificity may lead to more tests and patient anxiety. Many breast cancer survivors are not followed by oncologists, and their doctors may not be familiar with these recommendations. Oncologists also disregard the data. A plethora of both blood tests and nonmammographic imaging tests are frequently performed in asymptomatic women. The blood tests, marker studies, and advanced imaging techniques are expensive and, with limited health care funds, may prevent funding for more appropriate aspects of patient care. Abnormal marker studies lead to additional imaging procedures. Repeated CT scans and radionuclide imaging may induce a second cancer because of the radiation dose, and invasive procedures performed as a result of these examinations also add risk to patients without clear benefits. Improved adherence to the current guidelines can cut costs, reduce risks, and improve patient quality of life without adversely affecting outcome.

The average lifelong rate of developing a new primary lung cancer approximates 1% and 6% per year after radical therapy for non-small-cell lung cancer and small cell lung cancer, respectively. The frequency of recorded synchronous and metachronous lung cancers has been increasing in the recent years because of the development of early detection techniques and advances in cancer therapy. The distinction between multiple synchronous or metachronous primary lung cancers and intrapulmonary metastases is based on established clinicopathological criteria, however it is often difficult, although of great importance for the management and prognosis of these patients. Newly developed molecular and genomic methods are expected to contribute to a more solid and clear differentiation. Surgical treatment, whenever feasible, is considered the modality of choice for the management of patients with second primary lung cancers, as opposed to those with metastases. The type and extent of surgery are under discussion. The prognosis of patients with second primary lung cancers largely depends on the time of detection and the stage and location of the second cancer, thus surveillance after surgical resection of the initial tumor is mandatory.

Secondary cancer risk following radiotherapy is an increasingly important topic in clinical oncology with impact on treatment decision making and on patient management. Much of the evidence that underlies our understanding of secondary cancer risks and our risk estimates are derived from large epidemiologic studies and predictive models of earlier decades with large uncertainties. The modern era is characterized by more conformal radiotherapy technologies, molecular and genetic marker approaches, genome-wide studies and risk stratifications, and sophisticated biologically based predictive models of the carcinogenesis process. Four key areas that have strong evidence toward affecting secondary cancer risks are 1) the patient age at time of radiation treatment, 2) genetic risk factors, 3) the organ and tissue site receiving radiation, and 4) the dose and volume of tissue being irradiated by a particular radiation technology. This review attempts to summarize our current understanding on the impact on secondary cancer risks for each of these known risk factors. We review the recent advances in genetic studies and carcinogenesis models that are providing insight into the biologic processes that occur from tissue irradiation to the development of a secondary malignancy. Finally, we discuss current approaches toward minimizing the risk of radiation-associated secondary malignancies, an important goal of clinical radiation oncology.

This review describes the secondary cancer after radiotherapy. Secondary cancer is a great concern for cancer survivors, especially for childhood cancer survivors not only because of their intrinsic high susceptibility to radiation but also because of successful achievement of longer survival. Recent advance of molecular biology reveals unique genomic changes, which distinguish radiation-induced tumors from spontaneous or chemically induced tumors.

Women with contralateral breast cancer (CBC) have significantly worse prognosis compared to women with unilateral cancer. A possible explanation of the poor prognosis of patients with CBC is that in a subset of patients, the second cancer is not a new primary tumor but a metastasis of the first cancer that has potentially obtained aggressive characteristics through selection of treatment. Exome and whole-genome sequencing of solid tumors has previously been used to investigate the clonal relationship between primary tumors and metastases in several diseases. In order to assess the relationship between the first and the second cancer, we performed exome sequencing to identify somatic mutations in both first and second cancers, and compared paired normal tissue of 25 patients with metachronous CBC. For three patients, we identified shared somatic mutations indicating a common clonal origin thereby demonstrating that the second tumor is a metastasis of the first cancer, rather than a new primary cancer. Accordingly, these patients all developed distant metastasis within 3 years of the second diagnosis, compared with 7 out of 22 patients with non-shared somatic profiles. Genomic profiling of both tumors help the clinicians distinguish between true CBCs and subsequent metastases.

Penile cancer as primary disease is relatively rare in developed countries. The penis is a rare site of metastases in spite of its rich vascularization. Approximately 500 cases have been reported in the literature; almost 70% of primary lesions are of pelvic origin (from genitourinary or recto-sigmoid primary tumors). We describe a case of penile metastasis from lung cancer. The rarity of the event prompted us to also explore related reviews and discuss the incidence, physiopathology, diagnosis and therapy of penile secondary cancer.

Breast carcinoma is a heterogeneous disease. Clinical treatment of metastases from triple negative-Estrogen receptor-(ER(-), Progesterone receptor (PgR)(-), Human epidermal growth factor receptor 2(HER2)(-)) primary breast cancer and metachronous second cancer in visceral organs is different. In this article we report two cases of visceral metastases from two patients with Stage IV triple negative primary breast cancer. We presented morphology findings and immunophenotype of all lesions and we offered a practical recommendation for diagnosis of similar cases.

Allogeneic hematopoietic cell transplantation is associated with late adverse effects of therapy, including secondary solid cancers. Most reports address risk factors; however, outcomes after secondary solid cancer development are incompletely described. Our objective was to estimate survival probabilities for transplant recipients dependent on secondary solid cancer subtype. We used a previously identified and published cohort who developed secondary solid cancers following allogeneic transplant. Follow-up for these 112 previously identified patients was extended and their survival probabilities were studied. Median duration of follow-up from the development of secondary cancer for survivors was 11.9 years (range: 0.8-23.4) and 75% were followed >7.0 years. The 5- and 10-year overall survival probabilities were 50% (95% confidence interval (CI): 41-60) and 46% (95% CI: 37-57), respectively. Overall survival varied by secondary cancer type. Secondary cancer was the cause of death in most patients who died following development of melanoma, central nervous system, oral cavity, thyroid, lung, lower gastrointestinal tract and bone cancers. Extended follow-up allowed for the most comprehensive longitudinal evaluation to date of this rare condition. These findings will enhance clinicians' ability to predict outcomes and counsel transplant survivors who develop secondary solid cancers.

We employed a semi-Markov multistate model for the simultaneous analysis of various endpoints describing the course of breast cancer. Results were compared with those from standard analyses using a Cox proportional hazards model. We included 3,012 patients with invasive breast cancer newly diagnosed between 2001 and 2005 who were recruited in Germany for a population-based study, the Mamma Carcinoma Risk Factor Investigation (MARIE Study), and prospectively followed up until the end of 2009. Locoregional recurrence and distant metastasis were included as intermediate states, and deaths from breast cancer, secondary cancer, and other causes were included as competing absorbing states. Tumor characteristics were significantly associated with all breast cancer-related endpoints. Nodal involvement was significantly related to local recurrence but more strongly related to distant metastases. Smoking was significantly associated with mortality from second cancers and other causes, whereas menopausal hormone use was significantly associated with reduced distant metastasis and death from causes other than cancer. The presence of cardiovascular disease at diagnosis was solely associated with mortality from other causes. Compared with separate Cox models, multistate models allow for dissection of prognostic factors and intermediate events in the analysis of cause-specific mortality and can yield new insights into disease progression and associated pathways.
